Hey Product Hunt community! 👋 I created a website for first time home buyers 🔑 I recently started looking to buy my first home, and I found the whole process pretty overwhelming. There is so much information out there, but nowhere was there a single place that clearly explained everything. I was jumping between different calculators on various sites, constantly bumping into financial jargon and hidden details. For instance, I only realized quite late into the process that I had to account for a 10% deposit and bank guarantee costs. That is why I built , hoping to make things much easier for others going through the same journey. What you can do with HuisKoopWijzer: 💰 True Buyer Costs: Clear breakdowns of transfer tax rules, notary fees, valuation reports, and bank guarantees. 📊 Local Market Insights: Explore real time overbidding trends and square meter prices for 65+ Dutch cities. 🧮 Practical Calculators: Compare Rent vs Buy, calculate extra repayments, or structure family loans. 🤖 AI Housing Assistant: Get instant answers to complex Dutch real estate questions. 🔒 Privacy First: Completely free, no account needed, no data selling, and zero sales calls. Whether you are a local starter or an expat navigating the Dutch system, I would love for you to give it a try.
